The company said in a statement that Kia has taken proactive steps to address an engine manufacturing issue that can, in rare instances, result in a non-collision fire, including the recall of more than 680,000 vehicles, and is committed to taking any necessary actions in a timely manner.

But a consumer advocacy group wants a total 2.9 million Kias and Hyundais recalled including the 2011-14 Kia Sorento, Kia Optima, Hyundai Sonata and Hyundai Santa Fe; and 2010-15 Kia Soul.
